The main function of composite core material is to offer stiffness, strength, and continuity across a structure without considerably increasing weight. Whether a core material is over-molded with self-skinning decorative cover/flexible foam or fixed between two composite skins to create a sandwich panel, it acts as the foundation or core member of a structure. There are three popular close cell rigid foams: PVC foam , PET foam, PMI foam, PP honeycomb. The functionality of foam board mainly includes mechanical properties, thermal management, acoustics, combustibility and others.
JLON is an experienced manufacture of structural core materials, and have a range of core materials to fit any specification or manufacturing process. Structural stability of JLON core material makes resin matrix capable of high mechanical and thermal properties.
JLON core material is approved by DNV certificate. JLON has below core material:
Cross-linked PVC foam core, for the reticular structure of the molecular chain, consistent performance in all directions, with excellent specific stiffness, specific strength, compression, tension, shear, bending and other mechanical properties are excellent, can be combined with a variety of face materials to form a sandwich composites, which can greatly enhance the mechanical properties at the same time, almost no increase in weight, it is the ideal sandwich composites, has been widely used in the use of sandwich composites in Almost every field, including wind energy, marine (recreational sports, military, etc.), rail transport, new energy and other markets.
The main moulding method. phase transition of mixtures such as PVC from a viscous flow state to the formation of a polymer gel, and additionally, the decomposition of chemical blowing agents to form nitrogen, which dissolves in the polymer gel to form fine bubble cores. Through the reaction of isocyanate and water and further starting components, a polymerisation network is formed that can harden the PVC foam body (forming a reticulated structure), and ultimately the raw sheet is produced through processes such as expansion curing, and can then be processed into finished products such as slices.
JLON PVC foam core is a universal closed-cell, cross-linked polymer PVC foam formulated for durability, strength, and high processing temperatures. It is compatible with multiple resins and adhesives. It is an ideal core material for lightweight & high-strength composite sandwich structures and ideal for high-performance, lightweight composite applications.
It has a very low water absorption rate and excellent chemical resistance. It provides excellent fatigue resistance, impact resistance and very low water absorption. Heat and sound insulation are also very good.
